摘要：
The dinuclear copper(II) complex {[Cu(pmea)Cl][Cu(H2O)(3)Cl]}(Cl)center dot H2O (1) (pmea =bis(2-pyridylmethyl)amino-2-ethanoic acid) has been synthesized and characterized. It crystallizes in the monoclinic system P2(1)/c, a = 9.0057(11), b = 28.031(3), c = 8.5669(10) angstrom, beta = 104.267(2)degrees, V = 2095.9(4) angstrom(3), Z = 4. Crystal structure of 1 reveals a syn-anti carboxylate-bridged dinuclear complex, in which the coordination environment around each copper atom exhibits a distorted square-pyramid. Magnetic susceptibility measurement for 1 exhibits a weak intermolecular antiferromagnetic exchange interaction with 2J = -1.17(9) cm(-1). The cyclic voltammogram of 1 gives one oxidation and two reduction processes.
